Smaller turbo could help with turbo lag. Less inertia for rotation startup, so could help on the low end of the torque curve. Top end could be limited, however, by the RPM limit and the higher rotation speed of the smaller turbo at peak pressure. Higher altitude will require

The Mexico City GP is upon us, and as usual there are tons of questions about what effect altitude has on a race car. In this video I summarize for you all of the ways that race cars can be effected by the higher altitude of the Mexico City GP.

So who will benefit the most https://t.co/XpVx9yTZhK

Two different aero designs. The Merc is designed to hold out the turbulent front wake just outboard of the driver where it is widest, then aggressively tapers back. This aims to bring clean energy around the mid line of the sidepod through the undercut to the rear.

Ah yes. The gaiters I was speaking about in my previous post. The junction where these parts intersect is important aerodynamically and mechanically.

Excellent look at the split regions along the topside of the rear corner of the floor. You can see the air sticking to the undercut as it travels rearward.

The airflow near the floor edge naturally migrates to the low pressure region under the floor. The rear corner is where https://t.co/hNqG3wj7yZ

Have to believe that the gaitor update is part of the solution process to solving some of the performance degradation Max was discussing.

As far as I know, the gaitor is the elastomeric (or the like) flexible junction where dynamic suspension arms interface with static aero

Great technical explanations in here. Excellent piece.
